September 6, 20223 yr PMDG models require Dynamic Lighting in order for your lights to see the tarmac. Why do they insist on only making their lights work in this fashion, when Dynamic Lights is so heavy on performance? Does anyone know of an alternative to get PMDG lights working on the tarmac without Dynamic Lighting enabled? That would be awesome and I would never have to worry about turning on that performance hurting setting on again.
September 6, 20223 yr Usually you can get away with dialing AA back to 4xMSAA at night to help offset the hit from DL. SSAA and DL together can really clobber performance. The PMDG landing/runway turnoff/taxi lights are compiled into the .mdl files.

September 6, 20223 yr Performance problems with dynamic lighting are (IMO) more the fault of poor optimisation than anything else (and probably also having multiple shadows enabled). I run P3Dv4 @ 4x SSAA with dynamic lighting (but only internal shadows enabled) on my i5 7600k powered PC, and performance varies dramatically. It is pretty decent @ SimWings London Heathrow Professional with the iniBuilds dynamic lighting (and all of that scenery and autogen around London at Extremely Dense setting), and yet somehow the framerate when close to the terminal buildings @ MK Studios Dublin (again with the iniBuilds dynamic lighting) is very choppy indeed, and that only has the PlayHorizon VFR Photographic Scenery Volume 9 package (no autogen) being displayed outside the airport scenery. On a similar note, the dynamic lighting in my UK2000 airport packages may not be the most complex in the flight simulation world, but it does a good enough job, and I have zero performance problems at any of them.

September 6, 20223 yr Author Thank you for the suggestions. I personally don't find the cost benefit ratio of Dynamic Lighting to be worth the trouble. PMDG lighting the tarmac is pretty much the only time I ever need it. After years of each of us dealing with debugging P3D, I think we each have our theories of what causes the most crashes. One of them, for me, is this feature, which I have started disabling for all addons as well. So far so good. Just going to fly during the day on PMDG until I find a fix for lighting the tarmac. In exchange for leaving it off, I can also turn up all other settings with more confidence.
